• Cold weather conditions

Dust filters play a critical role in industrial processes, but when operating in colder environments, they face a significant challenge with condensation. Even if daytime temperatures are hot, overnight conditions can drop significantly, leading to cold filter surfaces. When warmer air cools against the cold surfaces of the dust filter, water vapour can condense, forming liquid droplets inside the unit. This moisture can cause dust to adhere to surfaces, building up and clogging the filter media, reducing efficiency, and ultimately risking costly downtime or damage.

• High temperature processes

Many industrial processes generate hot, moist air streams, such as drying systems, galvanising lines, or high-temperature manufacturing. When this warm process air meets a cooler filter surface, condensation can occur even when the outside temperature isn’t extremely low. Without proper protection, filters can experience moisture build up, damaging performance and efficiency.

• Type of dust collected

Fine powders, sticky particles from food or wood processing, and chemically active dusts are just a few types of dust prone to binding when exposed to even small amounts of condensation.

Trace heating

By applying electric trace heating cables to the filter’s structure, the metal surfaces are kept just warm enough to prevent condensation from forming. The system automatically regulates its temperature, providing continuous protection against the cold, without overheating. Once installed and properly insulated, the system safeguards the filters’ performance, even in the harshest winter conditions.
